TEMPERATURE PROGRAMMING RETENTION INDEXES - PREDICTION OF RETENTION TIME OF N-ALKANES IN PROGRAMMED-TEMPERATURE GAS-CHROMATOGRAPHY

In this work it is shown that it is possible to calculate programmed retention times of n-alkanes starting from three isothermal retention data. Different procedures which allow calculation of programmed retention time are also described and compared. Accuracy expressed as fractional difference was generally better that 1% in spite of the semplifications introduced in the calculation methods. All calculations can be performed with Basic programming on a personal computer.
